  • JTAG and boundary scan automatic chain selection
    Patent number: 7191265
    Abstract: A printed circuit board (PCB) may be used in a first mode where boundary scan techniques are used to externally program and/or test devices on the PCB, or a second mode where an internal source programs devices using boundary scan techniques. In one implementation, there is also additional flexibility to include or skip devices in a boundary scan chain and to accommodate non-scan related functions for pins used for scanning. These various modes of operation may be selected by activating and deactivating buffers.
